Decay-corrected excess lead 210 and caesium 137 activity concentrations for sediment core WP280

Bulk sediment samples of core WP280 were dried and homogenized. Samples were measured using a HPGe planar gamma detector in air-tight containers after the radioactive equilibrium between 226Ra (used as supported 210Pb proxy) and its daughter products had been reached. The efficiency calibration was...

Description
Summary:Bulk sediment samples of core WP280 were dried and homogenized. Samples were measured using a HPGe planar gamma detector in air-tight containers after the radioactive equilibrium between 226Ra (used as supported 210Pb proxy) and its daughter products had been reached. The efficiency calibration was performed by a direct transfer using reference materials with mineral matrix (IAEA-385 Irish Sea sediment and CANMET DL-1a Uranium-Thorium Ore with an addition of 137Cs certified solution) measured in comparable geometries. Downcore activities of 210Pbxs data were determined for the age model of core WP280. 137Cs activity depth profiles were used for validating the age model.
